End Cap (Compression)

End Cap Compression Fittings

Wet underfloor heating uses hot water circulated under high pressure to distribute heat, so watertightness is crucial to the efficient running of the system. And while leaks aren’t desirable in any water piping system, in underfloor heating, they can cause unseen damage under the floor. That’s why highly secure connectors, such as end cap compression fittings, are recommended.

We can't find products matching the selection.

High-Quality End Cap Compression Fittings for Secure Systems

Our WRAS-certified high-quality end cap compression fittings have a thermoplastic ring, which is compressed onto the pipe and held in place with a compression nut. The soft metal of the pipe is conformed to the fitting, forming a very effective seal. They’re made from high-quality plated brass with a double ‘o’ ring seal and are easily installed or disassembled with a spanner. While they’re ideal for wet underfloor heating, they can also be used for central heating and drinking water supply systems. We offer compression stop end caps in various sizes to suit your needs, alongside equal straight and male straight F1 compression fittings.
